The thermostat, also known as the temperature regulator, is a core component of a vehicle's cooling system. Its primary function is to intelligently adjust the coolant circulation path based on engine temperature, helping the engine quickly reach and maintain its optimal operating temperature range. A malfunctioning thermostat can easily cause engine overheating or prolonged low-temperature operation, both of which can cause irreversible damage to the engine. Below are detailed methods to check the thermostat's working condition.
